Patented Feb. 16, 1932 UNITED STATES PATENT OFFICE JOSEPH A. VOGEL, F W'IIMING'ION, DELAWARE, ASSIGNOR TO JOSEPH A. VOGEL COM- PANY, OF WILMINGTON, DELAWARE, A CORPORATION OF DELAWARE FLUSH TANK FOR WATER CLOSET SYSTEMS Application filed April 14,

This invention relates to improvements in storage tanks or receptacles and particularly to flush tanks for water closet systems. More particularly the invention relates to tanks of that type in which water under pressure entering the tank compresses air therein and is discharged for a flushing action under the forces of gravity and the air pressure.

The object of the invention is to provide a tank which may be easily and economically made, which will be of a neat and attractive appearance, and which is so constructed and reinforced that it may be made at low cost of light sheet metal and yet will be of great strength and durability.

The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which:

Fig. 1 is a front view of a flush tank embodying my invention.

Fig. 2 is a rear view of the same.

Fig. 3 is a central front-to-rear section through the tank.

Figs. 4 and 5 are front and top plan views of a wall bracket for supporting the tank.

In carrying my invention into practice, I provide a tank 1 of circular formation and comprising a cylindrical body portion 2 closed at front and rear by the walls or heads 3 and 4.

In constructing the tank, the body and walls of which are made of suitable sheet metal, the body 2 and front wall 3, which is integral therewith, are unitarily formed by a stamping or drawing action or in any suitable manner and by the use of suitable shaping means. A cup-shaped structure is thus produced which is closed at the front by the wall or head 3 and is designed to be closed at the rear by the separately formed wall or head 4.

In order to secure greater strength and ricaVo-convex form, the convex face of the wall 3 being outwardly disposed to give a desired finish to the structure. The rear wall 4 is made of a diameter to fit within the rear edge of the body 2 and is provided with an out- 1931. Serial No. 530,090.

wardly extending flange 5 lying parallel with i I the rear edge of the body and welded or riveted thereto. The convex side of the wall 4 faces inwardly and the concave side thereof rearwardly, so that a space bounded by the flange 5 is provided at the rear of the tank, thus disposing the wall 450 that, while its rear edge and the flange 5 will form a rim to abut against the wall of a room on which the tank is supported, the wall-4 of the tank will lie out of contact with the room wall.

The construction described provides a tank which is of simple type and easily manufactured, but in order to enable the tank to be formed of comparatively thinsheet metal, I provide reinforcing means for sustaining the walls 3 and 4 against all pressures and strains, thus allowing economical manufacture of a tank of great strength'and durability. To this end, I provide a reinforcing rod or like element 6 extending axially within the tank between the two walls 3 and 4 and welded, as indicated at 7,to said walls. Preferably the outer or forward end of this rod is threaded or otherwise fastened to an anchor member in the form of a disk or nut 8 which is welded to the head 3, while the rear end of the rod terminates in a threaded stem portion which projects through the head 4 and engagesan abutment disk or nut 9 which is welded to the head 4, whereby the rod is adapted to be first welded quickly and reliably to the wall 3 and then welded to the wall 4 after the latter has been placed in position and its flange portion 5 welded to the body 2. The rod 6 sustains the walls 3 and 4 against any tendency to relative outward movement or expansion due to internal pressures, as well as from any tendency to collapse under external pressures when the tank is drained of its fluid contents.

The tank is provided at its bottom with a nipple or like fitting 10 for connection with a combined water supply and discharge pipe. This pipe will be connected in practice with a water service system and the valve mechanism of a closet seat whereby, through movements of the seat, water will be admitted to the tank to compress the air therein and prime the tank for a flushing action, and the water then discharged for the flushing action under the combined forces of gravlty and the air pressure. In the event that the tank is to be provided internally with a galvanizing or other coating, the head 4 may be formed with an opening 11, through which the galvanizing solution admitted through the opening 10 may be discharged and the opening 11 then permanently sealed by a closure plug 12. The exterior of the tank may be galvanized, enameled, or otherwise coated or given any desired finish.

As before described, the tank is designed in practice to be supported for use upon a Wall or other surface in a room above and in rear of a toilet fixture, or in any other suitable position relative thereto. To enable it to be supported in position a wedgeshaped down-turned bracket arm 13 is provided upon the wall 4 near the top of the tank for engagement with a wedge-shaped keeper 14 in a supporting bracket 15 secured to the wall surface or support in the room. As the rear rim edge of the tank will rest against such wall surface and the head i will be spaced from such surface, the bracket members 13 and 15 will operate to support the tank firmly in position and such bracket members will be concealed from View and protected in the chamber or space bounded by the flange 5, thus enabling the tank to be securely mounted in a simple manner and in such manner that it may be readily taken down whenever required.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation and advantages of my improved flush tank will be readily understood without a further and extended description. lVhile the construction disclosed is preferred, it will, of course, be understood that changes in the form, proportion and details of construction of the parts may be made without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim is z- 1. A flush tank having water inlet and discharge means and a cylindrical body, a head formed integrally with and closing one side of the body, a separately formed head fitted and secured in and closing the opposite side of the body, and an axially disposed tie rod extending between and welded to said heads.

2. A flush tank having water inlet and discharge means and comprising a cylindrical body, a head formed integrally with and closing one side of the body, a flanged head fitted in the opposite side of the body and having its flange outwardly directed and secured to the body, and an axially disposed tie rod extending between and welded to said heads.

3. A flush tank having water inlet and discharge means and comprising a cylindrical body, a concavo-convex head integral with the body and closing one side of the body, said head having its convex surface outwar 1y directed, a separately formed concavoconvex head fitted in the opposite side of the body and having its convex side inwardly directed and its concave. side outwardly directed and provided with an outwardly directed flange secured to the body, and an axially disposed tie rod extending between and welded to said heads.

4. A fiush tank having water inlet and discharge means and comprising a cylindrical body, a head formed integrally with and closing one side of the body, a separately formed dished head fitted within and closing the 0pposite side of the body and having its concave face outwardly directed, an axially disposed tie rod extending between and welded to said heads, and a supporting bracket member secured to the convex face of the secondnamed head.

5. A flush tank having water inlet and discharge means and comprising a cylindrical body, a head formed integrally with and closing one side of said body, a head formed sep' arate from and fitted in and secured to the body and closing the opposite side thereof, and a reinforcing element extending between and welded to said heads.

In testimony whereof I afiix my signature.

JOSEPH A. VOGEL.
